Soda salinized soil modifier

Abstract

The invention discloses a soda salinized soil modifier which consists of the following raw materials in parts by mass: 40-50 parts of calcium silicate, 35-50 parts of humic acid, 1-5 parts of gluconicacid, 10-20 parts of glucose acetate, 10-15 parts of acetylated cellulose, 1-5 parts of ferrous lactate, 0.5-1 part of zinc gluconate, and 0.5-5 parts of ammonium glucurate. The modifier is capable of regulating a soil structure, reducing salt, removing alkali, loosening soil, promoting crop growth and increasing yield, and has the advantages of no toxicity, biodegradability and no secondary pollution, is easy and simple to implement, ecological and environmentally friendly, does not introduce inorganic acid radical ions, does not cause secondary salinization of the soil, is capable of regulating a soil structure, reducing salt, removing alkali, improving the soil fertility and improving the soil microbial activity, provides nutrients for plant growth, enhances disease resistance of cropsand increases the crop yield. Tests indicate that the relative reduction rate of pH of the soil is 8.3%, the relative reduction rate of the soil alkalinity ESP is 48.3% and the average yield of planted maize is increased by 41.2% after the soda salinized soil modifier is applied.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to an amendment for soda-type salinized soil. Background technique [0002] Saline-alkali land is an important land resource. The area of ​​saline-alkali soil in the world is about 1 billion hectares. my country has 99.13 million hectares, accounting for about 10% of the world's total. It is mainly concentrated in the arid and semi-arid areas of North China, Northwest and Northeast China . High groundwater level, high salinity, and capillary transpiration are important factors that cause land salinity, so that the soil surface contains a large amount of soluble salts such as sodium chloride and sodium carbonate, which can cause plant physiological drought, cell poisoning, and seriously affect crops. growth. Saline-alkali land Although the country has invested a lot of manpower, financial resources and material resources to improve saline-alkali land, it is still difficult ...

Problems solved by technology

These amendments have low nutrient content and short validity, ignoring the improvement of soil physical and chemical properties, and the survival rate of beneficial microorganisms is low, making it difficult to play a role

At present, the main problems in the improvement of saline-alkali land are as follows: secondary salt disasters and soil pollution are easily caused during the improvement process; there is a lack of high-efficiency chemical and biological amendments, which are difficult to apply and popularize; High-efficiency nutrients needed; crop emergence is not uniform, it is not easy to maintain seedlings, growth is thin; soil organic matter content is low, nutrient content is not high, the ratio of nitrogen and phosphorus is out of balance, organic fertilizer is insufficient, coupled with the cementation of calcium ions, the soil compaction is serious

In recent years, improving soil with organic amendments has become a hot topic in soil improvement research, because the common characteristics of salinized soil are low organic matter content, poor soil physical and chemical properties, many anions and cations harmful to crop growth, and low survival rate of beneficial microorganisms , the soil fertility is low, and the crops are not easy to promote the growth of seedlings
